Girardinichthys

Girardinichthys is a genus of splitfins that are endemic to Mexico. These highly threatened fish are native to the upper Lerma and Balsas basins, as well as water systems in the Valley of Mexico. Through man-made channels G. viviparus has been able to spread to the upper Pánuco River basin.[2][3] These small fish reach up to 6.5 cm (2.6 in) in length.[4] The name of this genus honours the American herpetologist and ichthyologist Charles Girard (1822-1895).[5]
